IMPROVD'VAULT-COVER.

Specification forming part of Letters Patent No. 88,504, dated March 30, 1869.

To all whom it may concern:

Be it known that I, GEORGE EI. PALMER, of the city, county, and State of New York, have invented a new and useful Improvement in (lovers for Openings in Sidewalks, Pavements, &c.; and I do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specitication.

`, This invention relates to a new and improved method of consti ucting the movable' or fixed covers for coal, gas, water, or other openings in sidewalks or streetlp'avements, whereby the danger ot' slipping upon them is prevented.

It consists in the construction ofthe covers as shown, and hereinafter more fully described.

In the accompanying plate ofdrawings, Figures 1,2,3,a`nd 4 are plan views of several different forms ot' my invention. Fig. 5 represents a central vertical section of a sidewalk or pavement with one form of my invention, also in section, in position therein. Fig. G is a like view, with another form of my invention, in section, in position therein.

Similar letters ofreference Yindicate corre spondingrparts.

rIhe cover, in all forms of my invention, consists of a dish, A, tilled with a single flag-stone, D,"as shown in the drawings, Figs. l, 2, and

5, 'or with bricks C, properly inasoned in, as

shown at Figs. 4 and (i, or with concrete E, as

shown at Fig. 3, or with blocks of wood or 0ther suitable material having, when finished, a rough or corrugated surface, or muy be, when preferred, filled with the same material as' the surrounding walk or pavement B.

The dish A may be made ot' cast-iron or other material having sufcient strength and emitiring qualities, either circular or rectangular in form, of Stich diameter or dimensions as to tit the opening to be covered, and of such depth inside as to receive the stone, brickconcrete, or other material in sufcient quantity. rlthe dish A is furnished on the outside, at the top,

with atlange, a, as shown, of sufficient widtlr only so as to prevent the said dish A from being forced through the pavement or walk B, and to prevent the vleaking of water around `the cover, said flange a being corrugated or The entire cover may `be. furnished, when required, with a ringand ring-bolt, e', or with two or more of such rings and ringbolts, by

means of which said cover may be con veniently 4 removed from or replaced upon the opening in the walk or pavement B.

The advantages ot' covers for openings in walks so made, as above shown and described, are that persons or animals walking over or upon the same Iare less liable to slip and' fall, and to injury from slipping and falling, than. by the use of the covers for such purpose now in-common use.

` rlhe cover should be so Vlet into the surround-- ing pavementgover the opening in the same, as,

when in position, to be level or even therewith, as shown in the drawings.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A cover for the openings in walks, pavements, Src., composed ofa dish, A, filled with stone, brick,concrete, artificial stone, wood, or other like materiahsubstantiallyas shown and described.

GEORGE H. PALMER.
